1.1 This specification establishes the requirements for copper-zinc-lead (leaded red brass or hardware bronze) rod, bar, and shapes of UNS Alloy Nos. C31400, C31600, and C32000 available for screw machine applications.

1.2 Units—The values stated in inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
